BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates generally to customization and control of features of a bathtub and specifically to remote control of features of the bathtub.

2. Description of Related Art

In conventional bath tubs, the temperature of the water entering the bath tub is controlled by manually turning on and off hot and cold water to enter the bathtub.

U.S. Pat. No. 9,326,326 describes customization of a bathtub with heating elements. The bathtub includes heated wall portions to provide an external heated surface of the bathtub. A composite pliable heat generating envelope is integrated into a wall of the tub for heating a wall of the bathtub. The envelopes can be placed at different portions of the bathtub to heat associated portions of the body, such as the neck, back and seat portion.

It is desirable to provide system for control of a bathtub providing remote customization of features of the bathtub including, for example, adjustment of the water level and temperature control.

In one embodiment, a water controller is connected to spigots of the bathtub. The spigots each being used for receiving hot or cold water. A drain controller can be connected to a drain of the bathtub. A water level sensor can be used for measuring the water level in the bathtub. A temperature sensor can be used for measuring the temperature of water within the bathtub. A heating element can be coupled or integrated into the bathtub to provide heating of water within the bathtub. A thermostat can be used for adjusting the heating element. A temperature controller can be connected to the thermostat. One or more of the water controller, the drain controller, the water level sensor, the temperature sensor, the thermostat and the temperature controller can be connected to a network.

DETAILED DESCRIPTION

Reference will now be made in greater detail to a preferred embodiment of the invention, an example of which is illustrated in the accompanying drawings. Wherever possible, the same reference numerals will be used throughout the drawings and the description to refer to the same or like parts.

FIG. 1 illustrates system for control of a bathtub 10 in accordance with the teachings of the present invention. Spigots 12 and 14 are associated with bathtub 16. For example, spigot 12 can receive hot water and spigot 14 can receive cold water. Water controller 18 is coupled to spigots 12 and 14. Water controller 18 can independently turn on and off spigots 12 and 14.

Drain controller 20 is coupled to drain 22 of bathtub. Drain controller 20 can close and open drain 22. Drain 22 can be closed when filling of bathtub 16 with water from spigots 12 and 14. Drain 22 can be open to remove water within bathtub 16. Water level sensor 24 can be used for measuring the water level in bathtub 16. In one embodiment, water level sensor 24 is placed on side wall 26 at a predetermined distance D1 from bottom 28 of bathtub 16. Water level sensor 24 monitors when the water level in the bathtub 16 reaches water lever sensor 24. Alternatively, water level sensor 24 can monitor the water level along the entire length of side wall 26 of bathtub 16.

Temperature sensor 30 measures the temperature of water within bathtub 16. Heating element 32 provides heating of water within bathtub 16. Heating element 32 can be coupled or integrated into bathtub 16. In one embodiment, heating element 32 is integrated within side wall 26 and/or bottom 28. A suitable heating element 32 is described in U.S. Pat. No. 9,326,326 hereby incorporated by reference into this application.

Thermostat 34 can be coupled to heating element 32. Thermostat 34 can be coupled to temperature sensor 35 which measures the temperature of heating element 32. Thermostat 34 can be used for measuring the temperature of heating element 32 and adjusting the temperature of heating element 32. Temperature controller 36 can be used to remotely control thermostat 34 and/or heating element 32. In one embodiment, temperature controller 36 is connected to network 40.

Network 40 connects to one or more of water controller 18, drain controller 20, water level sensor 24, temperature sensor 30 and temperature controller 36. In one embodiment, thermostat 34 can directly connect remotely to network 40. Network 40 for example can be a wifi network. Water controller 18, drain controller 20, water level sensor 24, temperature sensor 30, temperature controller 36 and thermostat 34 can include a wifi connection for connecting to network 40.

Device 50 connects to network 40. For example, device 50 can be a cell phone, tablet or laptop. Device 50 runs application 60. Application 60 includes application interface 62. Application interface 62 can display various features of bathtub 16 which can be controlled. Application 60 receives data from one or more of water level sensor 24, temperature sensor 30, temperature controller 36 and thermostat 34. Application 60 transmits control data to one or more of water controller 18, drain controller 20, temperature controller 36 and thermostat 34 for remotely controlling features of bathtub 16.

During operation of system 10, a user can select using application interface 62 various features of bathtub 16 to be controlled as shown in FIG. 2. For example, the user can select with application interface 62 to start water 70 flowing into bathtub 16. Application 60 can send control data to water controller 18 to adjust the amount that spigots 12 and 14 are opened. Water 70 can continue to flow until it reaches a pre-determined height of side wall 26 as sensed by water level sensor 24. Water level sensor 24 can send data of the water level to application 60. Application 60 can send control data to water controller 18 to close spigots 12 and 14 after it was sensed that water 70 reached a predetermined height.

The user can select with application interface 62 a temperature desired for water 70 to remain at during use of bathtub 16. Temperature sensor 30 can send data of the temperature of water 70 to application 60. Application 60 can send control data to temperature controller 36 or thermostat 34 to activate heating element 32 in order to maintain the desired temperature of water 70.
